CORPORATION OF MASSACHUSETTS SAFETY rm Application filed March 10, 1928 Serial No. 260,687.

My invention aims to provide improvements in safety pins.

In the drawings, which illustrate several preferred embodiments of my invention Figure 1 is a plan view of a non-swallowable safety pin showing a oi1e-piece bent wire pin with the guard loops interlocked;

Fig. 2 is a side elevation of the pin shown by Fig.1;

Fig. 3 is a plan view of a second form of non-swallowable safety pin showing the guard loops interlocked by a separate.ele-- ment;

Fig. 4 is a side elevation of the pin shown by Fig. 3;

Fig. 5 is a plan view of a non-swallowable safety pin showing the guard loops without the locking means; and

Fig. 6 is a side elevation of the pin shown by Fig. 5.

Referring to the drawings which illustrate -my invention,-I have shown safety pin constructions which are particularly, though not exclusively, adapted for fastening the clothes of children, particularly babies.

Many cases have occurred where a baby would put a loose pin into its mouth and swallow it or it would become lodged in the babys throat. Often an operation was re quired to remove the pin. It is to prevent such accidents that I have invented my non-' swallowable safety pin which is so proportioned that it is impossible for it to pass down into the throat of a human being.

Referring'to the embodiment of my invention shown by Figs. 1 and 2, I have illustrated the well known and commonly used type of safety pin. This pin is made of bent wire and has a body portion which includes the back portion 1 and the sharp pointed pin portion 2. In order to prevent swallowing i of such a pin I have provided guard means in the form of laterally projecting loops 3 extending transverse to the body portion. These loops 3 may be formed integral with the pin at any point. However, in Figs. 1 and 2 I have shown the loops as being formed by bending the wire, which forms the back 1,

in such a manner that the loops extend from the back '1 about midway between the ends of the pin. The wire is so bent that the loops are interlocked, as at A, to prevent distortion of the p1n.- Sullicient transverse distortion of the loops adjacent to the line of the back 1.

The pin illustrated by Figs. 3,and 4 is substantially the same as described in connection wlth Figs. 1 and 2 and therefore similar parts are provided with the same numerals.

While the loops 3 of the pin shown in Figs. 7

3 and- 4 are formed integral with the back portion 1 of the pm, I have not interlocked them in the same manner. In this instance, I have secured a plate 5 to the back of the pin by means of ears 6 which are bent around, the wire where the loops 3 join the back.

This plate 5 provides rigid means which prevent any lengthening of the back for the purposes described in connection with Figs. 1 and 2.

Figs. 5 and 6 illustrate a safety pin pro vided with the loops 3 to indicate a simple form of non-swallowable safety pin. This pin is the same as that described in connection with Figs. 3 and 4, except that the plate 5 has been omitted. So far as the non-swallowable idea is concerned, the loops 3 do not need to be interlocked.

The pins shown and described are safe for use as childrens as inexpensive.

my invention will be best understood by reference to the following claims.

Claims: 1. A'non-swallowable safety pin having a back portion, a pointed pin portion and interp-ins and are durable as well locked loops to prevent distortion formed integral with and extending laterally at each side of one of said portions to provide guard means for preventing swallowing of the said safety pin.

2. A non-swallowable safety pin having a back portion, apointed pin portion and guard ino means formed integral with and extending a substantial distance laterally from the said back portion between the ends to provide a guard against swallowing the said safety pin and means locking the said loops to gether to prevent distortion thereof.

3. A non-swallowable safety pin including the body proper of the pin and transverse projections extending from the body proper a sufiicient distance to prevent swallowing and means locking the said projections together to prevent distortion of the said safety pm.

In testimony whereof, I have signed my name to this specification.
